' CATCH-BASIN FOR-gDOWN-SPOUTS.

To all whom it may concern I Be it knownthatI, GEORGE E. MCGRATH, a citizen of the United States, and residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Catch- Basins for DownsSpouts, of which the following is a specification.

This invention relatesto improvements in catch basins or legs for pipes or spouts leading from the roofs of buildings for the purpose of conducting rain water and the water from melting snow therefrom, and it consists in certain peculiarities of the construction, novel arrangement and operation of the parts thereof, as will be hereinafter more fully set forth and specifically claimed.

These pipes or spouts carry with the water whichthey conduct from the roofs of buildings considerable gravel, when said roofs are of the gravel kind, and other kinds of solid matter when roofs of other character of materialare employed, and to prevent this gravel or other solid matter entering the sewers into which the water is finally discharged, said pipes are required by city or municipal ordinances to be equipped with or to lead to catch'basins-of the well known construction used in sewerage systems. As

is well known, such catch basins are locatedin the ground, and often at quite long distances from the down spouts or pipes, thus requiring, in many instances, the layingof drainage or tiling pipes leading from the lower ends of the down spouts to a catch basin. This is expensive, and besides, when tiling is used as drainage pipes, as above mentioned, the solid natterand gravel carried by the water will lodge at the joints of said pipes, thus causing them to become clogged or to require frequent cleaning, which is also an expensive item. The principal object of the invention is to provide a catch basin or leg for communication with or the interception of a down spout or pipe, which shall be extremely simple and inexpensive in construction, strong, durable and efficient in operation, which can be readily connected to the spout or pipe at any desired location or point thereon, in such a manner that it will eliminate all solid matter or sediment of a clogging nature from the water as it passes through the basin, in which it will be held until it is desired to remove the same therefrom. Another object is to provide the basin or leg Specification of Letters Patent.

with a detachable bottom which can be readily removed in order to clean. the basin.

In the accompanying drawing, which serves to illustrate an embodiment of the invention I Figure 1 is a vertical sectional view through the basin;

Fig. 2 is a horizontal plan sectional view taken on line 22 of Fig. 1, looking in the direction indicated by the arrows, and

Fig. 3 is a sectional view taken on line 33 of Fig. 1, looking in the direction indicated by'the arrows.

Corresponding numerals of reference throughout the vdiflerent views of the drawing refer to like parts. The reference numeral 5 designates the basin or leg which by preference is cylindrical in shape and may be made of cast iron or any other suitable material. At its upper end the basin or container 5 is provided with an inlet open: ing 6, surrounded by a slightly enlarged and upwardly extended sleeve or hollow portion 7, in which a portion of the down spout or pipe can be suitably secured. It will be noticed that the opening and the portion 7 are located at the wall of the container 5, and that the said container is provided in its upper portion, at a suitable distance below the opening 6, with an outlet portion orbranch 8-, to which another section of the down spout or pipe, or a drain pipe, may be connected, inany suitable manner. The outlet portion or branch may extend horizontally from the upper portion of the body of the basin or container as shown, or if desired, it may be deflected at its outer portion downwardly or laterally, but by preference it is arranged as shown in Fig. 1 of the drawing. Extended inwardly and down- ,wardly at a suitable angle from the lower inner portion of the outlet branch 8 is a baffle member 9, the inner or free edge of which terminates short of a vertical line drawn from the inner surface of the inlet opening 6, so that said baflie member will not interfere with the downward flow of the water from said inlet and from the down spout. It will be noted in Fig. 1 of lower end 01": the basin or container 5 is provided with an annular flange 12 which, by preference, has at suitable distances apart a number of slots 13 which are open at their outer ends for the ready insertion of headed bolts 14, which are employed to secure a closure or plate15 on the lower end of the basin or container, which closure or plate is provided at suitable points with openings to receive the bolts 14, by means of which and nuts engaging the lower ends of the bolts, the plate 15 is securely held in position. To prevent leakage a gasket 16 of any suitable material may be interposed between the flange 12 of the container and the plate 15 or closure therefor.

As shown in the difl'erent views of the drawing, the basin or container comprising the inlet portion 6, the outlet branch 8', and the baffle member 9, is made of a single piece, but I desire it to be understood that I do not desire to be limited to such construction.

In the operation of the device the water conducted by the down spout will enter the basin or container 5 vertically through the inlet opening 6 with considerable'force, especially if there has been a heavy fall of rain, or if the building to which the downspout is applied is a Very high one; and if the baflie plate 9 were not used it is manitest that the pressure of the downwardly passing water at the wall of the container opposite the outlet 8 would force the volume of water in the container, together with the gravel, solid matter or sediment therewith through said outlet, but by employing the baffle member arranged as shown the solid matter and gravel will be forced up against the inclined baffle member and for an instant will be pocketed or retarded in the chamber 11, from which it will fall to the bottom of the container, thus permitting the water to pass over the baflle and through the outlet, from which it may be led through a portion of the downspout, or a suitable pipe, to any desired point. It is obvious that after a considerable quantity of solid matter has been collected in the basin or container the closure or plate 15 can be readily removed byunscrewing the nuts and removing the bolts 14 from the flange l2 and from said plate, thus permitting the contents of the basin to be removed.

By the use of my improvements it is apparent that the pipe leading from the im proved catch basin need not necessarily connect with the common catch basins which are employed for other drains and often become defective or inefficient by reason of the accumulation of grease and other matter therein, but may lead directly to the main and serve to supply thereto a large quantity of practically pure water for flushing purposes.

Having thus fully described my inven'- tion what I claim as new and desire to secure by Letters Patent is= The combination with a downspout or con duit leading from the roof of a building downwardly and having an outlet portion, of a vertically elongated container intersecting'ly communicating with said spout or conduit between its inlet and outlet ends, said inlet being located in the upper end of the container near its wall and the outlet of said container being located below said inlet but also in its upper portion in the wall opposite that adjacent to the inlet, the container having an outwardly bellied portion directly below said outlet forming an inwardly open chamber, a horizontally disposed battle member extended inwardly and downwardly from the inner portion of said outlet above said chamber produced by the bellied portion and having its side edges in juxtaposition with the walls of the container on each side of said outlet, the free or inner end or the edge of said balfle plate terminating short of the path of the downwardly flowing water from the inlet and said end or edge being horizontally disposed. v v
